Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antisense compounds are used to inhibit WFDC2 expression, then cancer therapeutic effect is improved, but the lack of sufficient study and validation limits clinical application
Solution Approach 1:
The patent employs quantitative real-time PCR to measure WFDC2 mRNA levels and Western blotting to measure protein levels, creating a feedback mechanism to validate the therapeutic effect of antisense compounds. This systematic validation approach addresses the lack of sufficient study by providing measurable evidence of cancer therapeutic effect through multiple detection methods.
2Reliability
If modified oligonucleotides with multiple modifications are used, then stability and specificity are improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by introducing specific modifications at particular positions within the oligonucleotide sequence. Sugar modifications (2'-O-methyl, 2'-fluoro) are applied to enhance stability, while phosphorothioate backbone modifications are used to improve nuclease resistance. This localized modification strategy achieves enhanced stability and specificity without uniformly complicating the entire structure.
Solution Approach 2:
The antisense compounds utilize composite material principles by combining different modified nucleosides (2'-O-methyl, 2'-fluoro) with modified backbones (phosphorothioate) to create oligonucleotides with enhanced properties. This composite approach integrates multiple modification types to achieve both stability and specificity while managing structural complexity through systematic design.
3Adaptability or versatility
If antisense compounds are developed for multiple cancer types, then versatility is improved, but the lack of confirmed therapeutic effect across different cancers reduces reliability
Solution Approach 1:
The patent develops antisense compounds with universal applicability to multiple cancer types including ovarian, gastric, and colorectal cancers. The compounds are designed to target WFDC2 expression across different cancer contexts, demonstrating multi-functionality. This universality is achieved through systematic evaluation across various cancer cell lines and xenograft models.
Solution Approach 2:
The patent employs comprehensive validation through quantitative real-time PCR and Western blotting across multiple cancer types to confirm therapeutic effects. This feedback mechanism systematically verifies efficacy in ovarian, gastric, and colorectal cancers, building reliability evidence for the versatile application of antisense compounds across different cancer indications.
